Incidence of HPV infection is high among individuals in their late teens and early 20s. Thus, college students represent a historically high-risk group for HPV infection yet are also a group with the ability to independently access HPV vaccination for HPV prevention.

Article Synopsis
  • Hepatoblastoma is the most common liver tumor in children, typically diagnosed by age 3, with survival rates improving by 50% due to better treatment methods like chemotherapy and surgery.
  • A retrospective study on 16 pediatric patients revealed that those undergoing liver resection had a 100% survival rate after 30 months, compared to 65% for those who received liver transplants; most patients had elevated α-fetoprotein levels and required chemotherapy.
  • This study is significant as it represents the first report on hepatoblastoma treatments in Colombia and Latin America, supporting the effectiveness of surgical interventions for improving survival outcomes in young patients.

Introduction: One of the frequent complications suffered by patients with chronic renal failure is the lack of vascular access due to venous thrombosis. This means that the transplant surgeon must have a detailed knowledge of the intra-abdominal venous system, and other alternative surgeries, at the time of performing the renal graft implant, in order to ensure a good venous drainage.

Presentation Of The Case: This article provides a case report regarding a patient with no vascular access and with surgical difficulties at the time of the kidney transplant, in whom a renal-portal venous drainage was performed with very good outcome.

Background: Tobacco cessation among Latinos is a public health priority in the United States, particularly given the relatively high growth of this population segment. Although a substantial percentage of American Latinos use the Internet, they have not engaged in Web-based cessation programs as readily as other racial/ethnic subgroups. A lack of culturally specific advertising efforts may partly explain this disparity.

Anti-smoking Public Service Announcements (PSAs) typically emphasize the negative consequences of failing to quit smoking (negative frame), as opposed to emphasizing the benefits of quitting (positive frame). However, stressing the benefits of quitting sometimes produces better communication outcomes. Previous research on message framing has tried to identify factors affecting the impact of positive framing and negative framing.

Unlike previous emotional studies using functional neuroimaging that have focused on either locating discrete emotions in the brain or linking emotional response to an external behavior, this study investigated brain regions in order to validate a three-dimensional construct--namely pleasure, arousal, and dominance (PAD) of emotion induced by marketing communication. Emotional responses to five television commercials were measured with Advertisement Self-Assessment Manikins (AdSAM) for PAD and with functional magnetic resonance imaging (fMRI) to identify corresponding patterns of brain activation. We found significant differences in the AdSAM scores on the pleasure and arousal rating scales among the stimuli.

The purpose of this study was to understand the effect that individual characteristics have on consumer advertising processing under high- and low-interactivity circumstances on the Web. Tests on the relationship between individual differences and advertising responses form the basis of this empirical study on the Web. The results indicated that consumers have a higher tendency to avoid or experience ambivalence about Internet advertisements under low-interactivity circumstances, and attitudinal ambivalence lead to avoidance when responding to advertisements on the Internet.

Objective: We compared the effects of an arginine-supplemented diet with those of an isocaloric isonitrogenous diet on immune and metabolic response of children with burns.

Methods: This was a double-blind, randomized, placebo-controlled trial in a burn treatment center of a pediatric hospital in Santiago, Chile. All children (1-5 y of age) admitted within 48 h of a moderate to deep burn injury covering 10% to 40% of total body surface area were evaluated.

This article summarizes research published over the past decade and identifies areas where future research is needed to increase our knowledge of the media's role in fostering or reducing mental illness stigma. The following questions are addressed: (1) How is mental illness portrayed by the media? (2) How do media images of mental illness impact individuals' knowledge, beliefs, attitudes, and behaviors with regard to mental illness?
